The Cascade Range is an arc of volcanoes that extends from southwestern British Columbia to northern California. One of the six major composite volcanoes (formed by alternating layers of extruded lava and compacted ash) is Mount Baker in northern Washington. Close to the Canadian border, Mount Baker is about 85 miles north-northeast of Seattle and 65 miles southeast of Vancouver, British Columbia. This beautiful, snow-capped peak dominates the skyline from Bellingham, Washington to Vancouver, an...

|William Smith's Geological Map of England: Image of the Day - NASA -- NASA Image Of The Day|
Before the late eighteenth century, residents of England didn't necessarily take much interest in the rocks under their feet. The arrival of the Industrial Revolution, however, drew the attention of the country's entrepreneurs downward. England's industrialists began plunging deep underground for coal -- the fossilized remains of ancient swamps -- and carving canals across the countryside to transport it efficiently...

What will climate conditions around the world be like for the rest of this year? Some researchers are predicting an El Nino will arrive in the spring of 2002. The false-color image above represents a one-day snapshot of what conditions will be like on April 1, 2002, as predicted by a sophisticated NASA computer model. Developed by NASA's Seasonal-to-Interannual Prediction Program (NSIPP), this model actually links together three models in one--one each for geophysical dynamics within the atmosph...

In the western United States, water is the most critical natural resource. In addition to drinking supplies, water sustains agriculture, provides hydroelectric power, and nourishes ecosystems. The artificial Lake Powell and Lake Mead reservoirs on the Colorado River are the most important water caches in the West. Over the past several years, sustained drought has brought these reservoirs to unusually low levels, though not down to the record lows of the 1950s...

|Dark Dune Fields of Proctor Crater, Mars - NASA|
The dark rippled dunes of Mars' Proctor Crater likely formed more recently than the lighter rock forms they appear to cover, and are thought to slowly shift in response to pervasive winds. The dunes arise from a complex relationship between the sandy surface and high winds on Mars. Similar dunes were first seen in Proctor Crater by Mariner 9 more than 35 years ago. This image was taken by HiRISE camera on board the Mars Reconnaissance Orbiter, currently in orbit around Mars...

Many scientists regard receding glaciers as a symptom of global climate change. While certain types of glaciers -- such as surge glaciers and tidewater glaciers -- are actually expanding, there are many areas where scientists report glaciers are wasting away and that climate change is the culprit. For instance, 150 years ago there were 147 glaciers in Glacier National Park. Today, only 37 glaciers remain, and scientists say they will likely completely melt by the year 2030...

Alberto began as a tropical depression on the morning of June 10, 2006, having formed from an area of low air pressure over the northwestern Caribbean Sea. This depression moved generally northwestward through the Yucatan Channel between western Cuba and the Yucatan Peninsula and into the south-central Gulf of Mexico. The system was rather poorly organized as a result of southwesterly wind shear. This shear pulled the weather system from the rounded shape of a typical tropical storm and gave Alb...

In the Barents Sea north of Russia, marine plant life seems to be refusing to acknowledge that summer is passing and fall is approaching. On August 29, 2006, the Moderate Resolution Imaging Spectroradiometer modis.gsfc.nasa.gov (MODIS) on NASA's aqua.nasa.gov Aqua satellite captured this image of a dramatic bloom of phytoplankton (single-celled plants) swirling in the waters west of Novaya Zemlya (New Land)...

|Snow and Dust over Inner Mongolia : Image of the Day - NASA -- Provided by the seawifs.gsfc.nasa.gov/SEAWIFS.html SeaWiFS Project, NASA/Goddard Space Flight Center, and ORBIMAGE|
A severe snow-and-sand storm hit an 80,000 square-mile (205,000-square-km) stretch of the Chinese province of Mongolia on New Year's Eve, killing 21 people and leaving thousands of people to face possible starvation. The affected area is located about 250 miles (400 km) northwest of Beijing. It is the worst snowstorm to hit the region in more than 50 years. Lasting about 3 days, the storm dumped 24 inches (60 cm) of snow mixed with sand from the Gobi Desert, stranding many residents in deep drif...

Yearly snow cover can fluctuate widely over Earth's mountain ranges. Snowfall amounts, temperatures, cloud cover, and wind are just some of the factors that affect snow cover. Another factor, however, may sound surprising: dust. A study published in 2007 found that dust plays a significant role in the duration of snow cover in the San Juan Mountains of southwestern Colorado. Thomas Painter of the National Snow and Ice Data Center/University of Utah and his collaborators found that the area exper...

The sunlight dawdles a little longer at the end of each day, tiny bright green buds appear on trees and plants, and temperatures mellow: springtime is returning to the Northern Hemisphere. March 21, 2007, marks the first full day of spring, and the signs of its coming are evident everywhere, even from space. The green of new vegetation gradually creeps north, overtaking the winter brown that has covered the landscape for months...

|History Revealed - NASA|
More than 12 billion years of cosmic history are shown in this panoramic, full-color view of thousands of galaxies. This image, taken by NASA's Hubble Space Telescope, was made from mosaics taken in September and October 2009 with the newly installed Wide Field Camera 3 and in 2004 with the Advanced Camera for Surveys and covers a portion of the southern field of a large galaxy census called the Great Observatories Origins Deep Survey, a deep-sky study by several observatories to trace the evolu...

|Aerosol-Cloud Interactions: Image of the Day - NASA -- NASA images by Robert Simmon, Earth Observatory, based on data provided by Ilan Koren et. al., Goddard Space Flight Center|
Of all the things that influence Earth's climate, the tiny particles called aerosols may win scientists' award for ''least predictable.'' Not only do aerosols scatter, absorb, and reflect energy that enters and exits Earth's atmosphere, but they also tinker with the size, shape, and location of clouds and how much rain they produce. New research based on cloud and aerosol observations from the Moderate Resolution Imaging Spectroradiometer on NASA's Terra satellite demonstrates that when aerosols...
